There is a transfer afterOn today's ride, we'll be on all different path cycle routes in the Quy Nhon and Phu Yen provinces. In the morning, the tiny zig-zag routes will take you deeper into the remote hamlets and see the most challenging life of villagers living by mountainous hills. Race along sleepy rivers and Reunification trains on its railways and pass many colonial steel bridges still used in remote villages.

In the afternoon, the ride is on the country back road, through lush farmlands, rice paddies, a small market on the undulating paths through eucalyptus, a tiny town, and rice paddy fields to Da Dia reef. The area is about 100 meters wide and 250 meters long, with an estimated 35,000 columns of basalt rocks. The rocks are dark lava columns with roughly flat surfaces of different shapes - round, pentagon, hexagon, polygon etc. Ghenh Da Dia looks like a gigantic beehive or a pile of dinner plates, hence Ghenh Da Dia's name (The Sea Cliff of Stone Plates). These rock columns were created from volcanic eruptions millions of years ago; when the molten basalt flows met cold water, they solidified and shaped these rare polygonal formations due to thermal contraction effects. Then we bike to seaside villages in the afternoon and continue cycling on undulating paths through the sweet potato tapioca plantation to Tuy Hoa city.
